Richard Rainwater got his start as a prolific Texan investor at age 26 managing assets and making billions for the Bass family in the 1970s. The Stanford Business School grad broke out on his own in 1986, minting his own billion-dollar fortune. He later quipped: "I'm just a retired guy who made a couple billion by being in the right place at the right time." His mentorship helped spark the careers

of fellow billionaires Eddie Lampert and David Bonderman. Rainwater has been stricken with a rare neurodegenerative disease, supranuclear palsy, since 2009. Richard and his family, through the Rainwater Charitable Foundation, have funded an effort called the Tau Consortium that is researching a cure, investing more than $50 million over the past five years. Rainwater's wife, Darla Moore, was a well known investment banker in her own right. She has been a benefactor to her alma mater, University of South Carolina, home of the Darla Moore School of Business. In 2011 she donated $5 million for a new aerospace research center at the school. Moore was one of the first two women admitted as members at Augusta National Golf Club in 2012, along with Condoleezza Rice.
